A person who possesses a controlled dangerous substance that was prescribed or dispensed lawfully may possess it only in the container in which it was dispensed; except that the person may possess no more than a 10-day supply in other than the original container if the person produces, upon the request of a law enforcement officer, the name and address of the practitioner who prescribed the substance or the pharmacist who dispensed it. A person who violates this section is a disorderly person.
